GRAL is a library for creating high quality plots and charts in Java. Many plot types are available like scatter plot, bubble plots, line plots, area plots, pie charts, and bar charts. Additionally, GRAL can exchange and process data (smoothing), and various plug-ins allow the import and export of data and graphics to formats like CSV, JPEG, PNG, EPS, PDF, or SVG.

This release brings support for arbitrary data types for data sources, improved statistics and import functionality, two new plot types (box-and-whisker, raster), support for automatic axis scaling and secondary axes, greatly-improved interactive navigation, localization, better documentation, and numerous bugfixes
